They're good for the budget you have. They're very good bang-for-buck, unlike Intel which while more powerful is much more expensive.
MW2 it will play well, Crysis will run not-as-well but pretty good
ok cool ill think about getting these parts btw when i get more cash and i feel that the processor isnt good enough will i be able to upgrade it to a more powerful AMD? or will i need to buy another mobo?
